effect of Parsley petroselinum crispum intake on urinary apigenin excretion blood antioxidant enzymes and biomarkers for oxidative stress in human subjects
British Journal of Nutrition, 1999Co-Authors: S E Nielsen, Pia Knuthsen, Jette F Young, Bahram Daneshvar, Soren T Lauridsen, Brittmarie Sandstrom, Lars O DragstedAbstract:Seven men and seven women participated in a randomized crossover trial to study the effect of intake of Parsley (Petroselinum crispum), containing high levels of the flavone apigenin, on the urinary excretion of flavones and on biomarkers for oxidative stress. The subjects received a strictly controlled diet low in flavones and other naturally occurring antioxidants during the 2 weeks of intervention. This basic diet was supplemented with Parsley providing 3·73‐4·49 mg apigenin/MJ in one of the intervention weeks. Urinary excretion of apigenin was 1·59‐409·09 mg/MJ per 24 h during intervention with Parsley and 0‐112·27 mg/MJ per 24 h on the basic diet (P , 0·05). The fraction of apigenin intake excreted in the urine was 0·58 (SE 0·16) % during Parsley intervention. Erythrocyte glutathione reductase ( EC 1.6.4.1; GR) and superoxide dismutase (EC 1.15.1.1; SOD) activities increased during intervention with Parsley ( P , 0·005) as compared with the levels on the basic diet, whereas erythrocyte catalase ( EC 1.11.1.6) and glutathione peroxidase (EC 1.11.1.9) activities did not change. No significant changes were observed in plasma protein 2-adipic semialdehyde residues, a biomarker of plasma protein oxidation. In this short-term investigation, an overall decreasing trend in the activity of antioxidant enzymes was observed during the 2-week study. The decreased activity of SOD was strongly correlated at the individual level with an increased oxidative damage to plasma proteins. However, the intervention with Parsley seemed, partly, to overcome this decrease and resulted in increased levels of GR and SOD. Apigenin: Antioxidant status: Urinary excretion

The fraction of apigenin intake excreted in the urine was 0.58 (SE 0.16)% during Parsley intervention.

floral induction production and seed quality of Parsley cultivars as influenced by plants vernalization periods inducao floral producao e qualidade de sementes de cultivares de salsa em funcao de periodos de vernalizacao das plantas
Bioscience Journal, 2015Co-Authors: Cibele Chalita Martins, Carla Gomes Machado, Mauricio Feis Ganz Sanches, Juliana Faria Dos Santos, Roberval Daiton VieiraAbstract:In the production of Parsley ( Petroselinum crispum ) seeds is recommended the cultivation in locations of low temperatures to permit the emission of floral stalk. The study aimed to verify the effect of vernalization on floral induction, production and quality of Parsley seeds. Ten plants of three cultivars (Caipira, Chacareira and Lisa Grande Portuguesa (O. Enke)) grown in pots for six months were submitted to vernalization at 5 °C for 0, 15, 30 and 45 days. After treatment, the plants were transferred to greenhouse and evaluated for period and flowering percentage, seed yield per plant and seed quality. The seed quality was evaluated by weight of a thousand seeds, germination (percentages of normal and abnormal seedlings, dormant and dead seeds), first count of germination, accelerated aging, dormancy after accelerated aging, seedling emergence in the field and seed water content before and after accelerated aging. It was concluded that the vernalization does not promotes floral induction and production of Parsley seeds. For Lisa Grande Portuguesa (O. Enke) cultivar, the vernalization of the plant for 30 days enables the production of seed with high germination and vigor. Parsley seeds dormancy can be caused by plants vernalization periods between 30 and 45 days depending on the cultivar, followed by the exposure of the seeds to the conditions of high temperature and relative humidity of the air (41 °C/100%, UR/72 h).

Composition of flavonoids in fresh herbs and calculation of flavonoid intake by use of herbs in traditional Danish dishes
Food Chemistry, 2001Co-Authors: Ulla Justesen, Pia KnuthsenAbstract:Abstract Many herbs are known as excellent sources of natural antioxidants, and consumption of fresh herbs in the diet may therefore contribute to the daily antioxidant intake. The present study was performed in order to quantify flavonoids in commonly eaten fresh herbs. Fifteen fresh herbs (basil, chives, coriander, cress, dill, lemon balm, lovage, oregano, Parsley, rosemary, sage, spearmint, tarragon, thyme, and watercress) were analysed by HPLC and mass spectrometry. Five major flavonoid aglycones were detected and quantified by HPLC after acid hydrolysis: apigenin, isorhamnetin, kaempferol, luteolin, and quercetin. The highest levels of flavonoids were found in Parsley (510–630 mg apigenin /100 g), lovage (170 mg quercetin/100g), mint (18–100 mg apigenin/100 g), and dill (48–110 mg quercetin/100 g). Mass spectrometric detection, using atmospheric pressure chemical ionisation (APCI), was used to verify the presence of flavonoids in the hydrolysed extracts of herbs. Some traditional Danish dishes contain herbs, particularly Parsley, dill, cress and chives, and the contribution to the flavonoid intake by consumption of these dishes was calculated.

The study aimed to verify the effect of vernalization on floral induction, production and quality of Parsley seeds. Ten plants of three cultivars (Caipira, Chacareira and Lisa Grande Portuguesa (O. Enke)) grown in pots for six months were submitted to vernalization at 5 °C for 0, 15, 30 and 45 days. After treatment, the plants were transferred to greenhouse and evaluated for period and flowering percentage, seed yield per plant and seed quality. The seed quality was evaluated by weight of a thousand seeds, germination (percentages of normal and abnormal seedlings, dormant and dead seeds), first count of germination, accelerated aging, dormancy after accelerated aging, seedling emergence in the field and seed water content before and after accelerated aging. It was concluded that the vernalization does not promotes floral induction and production of Parsley seeds. For Lisa Grande Portuguesa (O. Enke) cultivar, the vernalization of the plant for 30 days enables the production of seed with high germination and vigor. Parsley seeds dormancy can be caused by plants vernalization periods between 30 and 45 days depending on the cultivar, followed by the exposure of the seeds to the conditions of high temperature and relative humidity of the air (41 °C/100%, UR/72 h).
